/* ** ** Swift/XRT hardness ratio for Cen A. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 56021.396711 0.000590 12.37887 3.31965 0.96569 0 0.22000 0.05685 0.16243 0.04194 2.72335 0.19524 2.01020 0.14403 56021.397842 0.000541 11.60330 3.08144 0.97861 0 0.24665 0.06308 0.18789 0.04803 2.86190 0.20488 2.17210 0.15546 56021.398899 0.000515 12.86790 3.55871 0.97753 0 0.23462 0.06271 0.17864 0.04774 3.01909 0.21452 2.29933 0.16337 56021.399981 0.000567 13.30654 3.83202 0.99490 0 0.19819 0.05525 0.15090 0.04208 2.63721 0.19067 2.01489 0.14565 56021.401115 0.000567 8.85097 2.14467 0.97449 0 0.30580 0.07077 0.23410 0.05418 2.70663 0.19422 2.07064 0.14858 56021.402313 0.000631 11.52399 3.04973 0.97248 0 0.21086 0.05372 0.16090 0.04097 2.42992 0.17411 1.86797 0.13384 56021.403459 0.000515 17.73823 5.94018 0.98315 0 0.16593 0.05426 0.12645 0.04139 2.94331 0.21213 2.25108 0.16224 56021.404486 0.000512 13.83298 3.97906 0.98305 0 0.21655 0.06036 0.16572 0.04621 2.99552 0.21285 2.29933 0.16337 56021.405554 0.000556 12.25109 3.18459 0.96354 0 0.23074 0.05769 0.17612 0.04403 2.82687 0.20116 2.15981 0.15368 56021.406867 0.000758 23.85481 7.37100 0.95420 0 0.12876 0.03905 0.09748 0.02957 3.07146 0.18124 2.32721 0.13732
